Vibration-Resistant Compression Fittings for Stainless Steel Tubing
- For Use With: Acetylene, Air, Butane, Compressed Air, Cutting Oil, Diesel Fuel, Fuel Oil, Gasoline, Helium, Hydraulic Fluid (Petroleum Base), Kerosene, Mineral Oil, Natural Gas, Nitrogen, Propane, Soap Solutions
- Temperature Range: -10° to 400° F
- Tubing: Use with seamless 316Ti or 321 stainless steel
- Specifications Met: DIN 3861
Instead of a metal sleeve (ferrule), these fittings have a rubber sleeve that cushions tubing and absorbs vibration to maintain a tight seal, even when connected to large pumps. However, rubber sleeves can’t withstand temperatures as high as metal ones. To create the strong seal, tighten the included nut. These fittings are made of 316 stainless steel, so they have excellent corrosion resistance. They’re also known as flareless fittings. All meet DIN 3861, which is an international standard for compression tube fitting specifications.
BSPP and metric male threads have a gasket to prevent leaks.

Nuts for Ultra-High-Polish Gasket Fittings for Stainless Steel Tubing
- For Use With: Argon, Helium, Nitrogen
- Temperature Range: -420° to 1000° F
- Tubing: Use with 316/316L stainless steel
- Compatible With: Swagelok® VCR
Nuts are 316 stainless steel for excellent corrosion resistance.
To connect two butt-weld adapters, use a male nut and a female nut. To connect a threaded adapter or a Yor-Lok adapter with a butt-weld adapter, use a female nut. Nuts and adapters are sold separately.

The 15 Ra finish on the interior of these fittings creates an ultra-smooth surface. Also known as ultra-high-purity fittings, they are packed in a Class 100 clean room to prevent contamination. They are commonly used in semiconductor applications. Fittings use a metal gasket (sold separately), which generates fewer particles than a rubber gasket and creates a strong seal in high-pressure and high-vacuum applications. Fittings are 316 stainless steel for excellent corrosion resistance.

Transfer liquids and gasses into high-vacuum chambers with these assembled fittings, also known as feedthroughs. Because they form a tight seal on chamber walls, they are often used in coating, cooling, and leak-testing applications where negative pressure (vacuum) must be maintained. These fittings are ready to install and include high-vacuum fittings, metal tubing, and Yor-lok tube fittings. On each end, the Yor-lok fittings include a nut and two sleeves that grip your system’s stainless steel tubing. The entire assembly is stainless steel, so it resists rusting. These fittings are not for use in pressure applications.
Quick-clamp fittings meet ISO 2861, which specifies the dimensions of quick-clamp high-vacuum fittings, clamps, and rings to ensure vacuum tightness. These fittings require a clamp and ring (each sold separately) to complete the connection.
Flanged fittings require a gasket and bolt kit (each sold separately) to complete the connection.
